How can I copy files from my usb on Meego Pre Alpha

Hey pals,
I hope you can help me with this,
I would like to know how can I copy my music and pictures files into my Meego system, after mounting it from a usb...
I cant listen and watch my files while the pendrive is mounted but once I remove it from the usb port, the files disappear, so I don't know what to do, to keep it in my tablet
thanks!
